First are the nose and feet. The nose swells to ridiculous proportions to the face, the bridge leading upward, recalling any breaks in earlier childhood. Their face will probably never grow to the full proportions of that nose, but this is good. The feet go at about this time as well, going through 6 shoe sizes in a matter of two or three months. Similar to the lionpaws on a Golden Retrieverpuppy, you know by looking at them that they will have to (in relatively short order) support a much larger animal. Any chance at Coordination is entirely gone at this point, and will not return for at least a year.

At this time, the voice starts to go, although this is less predictable. It may have started a while ago. It probably already richened out of little boy soprano, depending on the end destination, into an Alto or a Tenor. If it hasn't already it will at this point it will finish its dive down to tenor, baritone or Basso range.

Next come the rest of the extremities - namely the arms and legs. I swear it must be that one morning these 15 year old boys wake up and their arms and legs are 6" longer than when they went to bed the night before. Watching them, they now lope instead of walk. Legs and feet have a tendency to catch on unwatched for things, or each other. Arms are folded cautiously in towards the body; shoulders folded down and forward in protective bad posture. Trying to sit in chairs used the day before becomes a chore. The extra long limbs must be folded and tucked and turned in strange awkward ways to fit into desks at school or into cars or seats on buses.

This becomes a period of perpetual bad posture and pants that don't fit, because the rest of the body has years before it catches up. Slowly the shoulders will Broaden, cheekbones and jawbones and Brow ridges show up. They will adjust to their new limb length. Gain 30 or 40lbs so that they are no longer the 90lb Weakling, but the 120lb skinny boy.
